IMPROVEMENT IN PLASTERING-BOARDS FOR WALLS, &c.

Specification forming part of Letters Patent No. vLIL-531, datedFebruary 17, 1874; application filed July 25, 1873.

To all `whom -tmuy concern:

Be it known that l, LoRENcE HENRY 'liDE- MAN, ot' Jamestown, in thecounty of Chautauqua and State of New York, have invented certainImprovements in Finishing` House lWalls and Ceilings, ot' which thefollowin g is a specification:

The object of my invention is to do away with lath and plaster inhouses, and furnish in its stead a cheaper and better mode ot'linishing, and one that overcomes the objections ot' being damp,crumbling, cracking, or breaking; and to enable others skilled in theart to make and use my invention, I will proceed to describe itsconstruction, reference being had to the accompanying drawings withletters of reference thereon, in which- Figure 1 represents a fronteleyation, and Fig. 2 a vertical section, ot' my invention.

ln a brick house, A represents a rough brick wall, on which I nail orsecurely fasten strips oi' boards B, at suitable distances apart, andaround the edges 0r"'corners of the room strips at right an gles. It isnot essential that these strips be ot' unit'orm width or distance apart;but they should -bc ot` the same thickness and have their face cornersrounded a little.

I then procure what is known as burlaps7 (j, which is a strong, coarse,hemp cloth, and, at'ter sewing its breadths together, stretch it tightlyover these strips and securely tack or ltis then ready for paper, whichis put on the same as onan ordinary wall, and may afterward beialeimined, frescoed, or decorated in any manner desired, the same asother walls.

On ceilings, I do not put on any strips, but stretch the burlaps andnail it to thejoists.

On frame buildings l board the inside with any rough boards and thennail on the strips the same as described on brick walls.

Thus, it will readily be seen that in frame houses I have two dead-airchambers, and in brick houses one, which makes the houses cooler insummer and warmer in winter, and entirely prevents dampness, or souringand molding of walls.

rIhe reason why I use bui-laps is because of its great strength anddurability. It also holds the paper rmer than common plastering, andadapts itself readily with the paper to the different degrees of drynessor moisture in the atmosphere, so as always to keep smooth, and as 'itonly costs ten cents a yard, the actual cost of vinishing in this manneris less than half the amount of lath and plaster.

The reason why I round the corners of strips is, so that it may not showwhen papered where these strips are.

My invention is particularly valuable on ceilings that are subject tojar and spring, as it does to perfection on such places where plasteringwould not stay for anylength of time, and as a room or house may beiinished and used the same day, it saves all delays, eX- pense, andtrouble incident in waiting for plasteringI to dry, and also the ruiningof life and health caused by damp walls.

The burlaps may have a coat or preparation applied to its inside, so asto eectnally eX- clude mice or vermin. i

I am aware that it has been common to linish walls by putting paper orwood hangings upon a backingvot' cotton cloth; and, therefore, I do notclaim, broadly, the combination ot' paper with a iibrous backing fortinishing walls. Cloth ot' cotton is found to be objectionable, becauseit yields readily to atmospheric influences, and soon becomes loose andunsightly. The material known as burlaps, as above set forth, I havediscovered to be free from the above-named defects.

ll'aving described my invention, what I claim as new is- Y l. rIhcimproved plastering-board asa substitute for lat-h and plaster in thewalls and ceilings of houses, consisting of the combination ot' a hempfabric known as burlaps7 and a paper or other ornamental facing appliedI'or use substantially in the manner described.

2. In combination with a librous backing and facing of paper or otherornamental material, C and C', the strips B with rounded corners, as andfor the purpose set forth.
